MIOHAELVJ. MGEWAN, OF NEW YORK, N. Y.

IMPROVEMENT IN WATER-CLO$ET 'S.

Specification forming part of Letters Patent No. 187,545, dated February20, 1877 application iiled August '7, 1876.

To all whom it may concern:

Be it known that l, ll/IIGHAEL J. MOEWAN, of the city, county, and Stateof New York, have invented a new and Improved Water Closet, of which thefollowing is a specification:

Figure 1 is a vertical section on line .r 00 in Fig. 2, and Fig. 2 is aplan view.

Similar letters of reference indicate corresponding parts.

This invention consists in the arrangement of a sliding valve at thebottom of a closetbowl, for dropping the contents of the bowl into thetrap, andt'or preventing the rising of effluvia from the trap or sewerbelow.

A represents an ordinary Water-closet bowl, which is fitted to a plate,B, that forms the cover of the slidevalve casing. O is the casingattached to the trap G, and containing a slide-valve, Ct. D is a tubeextending from the casing in line with the valve, and having astuffing-box, I), at its outer end. A rod, 0, is attached to the valveto, and runs out through the stuffing-box b, andis provided with an eye,d. E is .a spring, resting against the stuffing-box b, and pressingagainst the valve a. The valve is of sufficient size to close thepassage from the bowl into the trap. f is a rubber packing'ring, whichthe valve presses when it is closed, making an airtight joint.

F is the ordinary knob for operating the valves of the Water-closet,which is connected by the cord or chain g with the rod 0. The valve isopened by pulling the knob F when the excrementitious matter and Waterare allowed to pass out into the trap G. The spring E returns the valveto its seat.

Any ordinary device may be used to control the supply of water to thebowl. The advantages claimed t'or this invention are, that the slidingvalve takes the least possible amount of room, and as a consequencethere is no chamber for the accumulation of gases. The valve forms atightjoint with the rubber packing, and prevents the rising of efiuvia.

Having thus described my invention, I claim as new and desire tosecureby Letterslatent 1. The casing G and tube D, arranged as shownwith respect to bowl A, and provided With slide-valve having spring e,as shown and described, for the purpose specified.

2. The combination of the valve a. packing f, casing 0, tube D,stuffing-box 1), rod 0, spring E, bowl A, and trap G, substantially asspecified.
